IMO having to manually track where a dependency that requires higher
msrv is used is *much* harder and error prone than declaring that relation
for where it's actually used. I.e., with your patch we're still missing
PDM, pve-rs, ...?

On the contrary, if you declare dependency info for proxmox-fixed-string,
then debcargo will automatically generate a d/control dependency relation
like:

 rustc:native (>= 1.87) <!nocheck>,

Thus everything using that as build-dependency will get ensure the
correct rustc version is installed for all users of that crate, not
just one.
